set SW1[1:8] = '00010011', SW2[1] = '1', SW3[4] = '0' for NOR boot
Switching between default bank and alternate bank on NOR flash
To change boot source to vbank4:
via software: run command 'cpld reset altbank' in U-Boot.
via DIP-switch: set SW3[5:7] = '100'
To change boot source to vbank0:
via software: run command 'cpld reset' in U-Boot.
via DIP-Switch: set SW3[5:7] = '000'

a. build PBL image for NAND boot
$ make T2080RDB_NAND_config
$ make
b. program u-boot-with-spl-pbl.bin to NAND flash
=> tftp 1000000 u-boot-with-spl-pbl.bin

=> mmc write 1000000 8 0x800
set SW1[1:8] = '00100000', SW2[1] = '0' for SD boot
2-stage NAND/SPI/SD boot loader
-------------------------------
PBL initializes the internal CPC-SRAM and copy SPL(160K) to SRAM.
SPL further initializes DDR using SPD and environment variables
and copy U-Boot(768 KB) from NAND/SPI/SD device to DDR.
Finally SPL transers control to U-Boot for futher booting.
SPL has following features:
- Executes within 256K
- No relocation required

Device tree support and how to enable it for different configs
--------------------------------------------------------------
Device tree support is available for t2080rdb for below mentioned boot,
1. NOR Boot
2. NAND Boot
3. SD Boot
4. SPIFLASH Boot
To enable device tree support for other boot, below configs need to be
enabled in relative defconfig file,
1. CONFIG_DEFAULT_DEVICE_TREE="t2080rdb" (Change default device tree name if required)
2. CONFIG_OF_CONTROL
3. CONFIG_MPC85XX_HAVE_RESET_VECTOR if reset vector is located at
CONFIG_RESET_VECTOR_ADDRESS - 0xffc
If device tree support is enabled in defconfig,
1. use 'u-boot-with-dtb.bin' for NOR boot.
2. use 'u-boot-with-spl-pbl.bin' for other boot.
